The 138 mm width and 248 mm height fit standard MCCB panel cutouts; depth at 110 mm leaves room for rear-connection hardware. This is a line-protection design (not motor-protection), so the thermal-magnetic curve is shaped for feeder and distribution duty. The integrated shunt trip (STL) and two HQ auxiliary switches let you wire remote trip and status feedback into the safety circuit or PLC without adding external accessories. The 3VA2340-7HL32-0KC0 carries a 330 kA interrupting rating at 240 V, dropping to 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V. That steep roll-off above 500 V is typical for a 400 A frame — the arc energy at 690 V limits the interruption capability. For a 480 V distribution panel in North America, the 187 kA figure still handles most high-fault scenarios. ## Thermal derating — continuous current across the ambient range At 55 °C it derates to 385 A, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C.","metaTitle":"Siemens 3VA2340-7HL32-0KC0 SENTRON MCCB, 400A, 3-Pole, 330kA","metaDescription":"Siemens SENTRON 3VA2340-7HL32-0KC0 molded case circuit breaker, 400A continuous, 3-pole, 330kA breaking at 240V.

The 3VA2340 frame is physically larger (138 mm wide, 248 mm tall) than the 3VA2116 frame, so it will not fit the same panel cutout or bus bar spacing without mechanical modification. The wiring schematic for the shunt trip and auxiliary switches is functionally similar, but the physical swap requires re-termination."},{"question":"What compliance documentation does this brand provide for 3VA2340-7HL32-0KC0?","answer":"Siemens SENTRON MCCBs carry IEC 60947-2 certification as standard.
